' WINDOW-FASTENER.

Application filed April 19, 1915.

To all whom it may] concern:

Be it known that I, WILLIAM HrMoAn- LISTER, a citizen of the United States, residing at Newberry, in the county of Lycoming and State of Pennsylvania, have in vented certain new and useful Improvements in Window-Fasteners; and'I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in apparatus for holding and locking window sashes and frames and consists of a simple and efiicient device of this nature having various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which:

Figure 1 is a sectional view through a frame of a window showing in elevation the operative parts of my invention. Fig. 2 is a sectional view on line 2-2 of Fig. 1. Fig. 3 is a section on line 33 of Fig. 1. Fig. 4 is a detail perspective view of a part of the invention.

Reference now being had to the details of the drawings by numeral, 1 designates a window frame, 1 the sill and 3 the sash, said frame having a recess 2 formed therein, as shown clearly in Fig. 2, and the adjacent edge of the window sash has a recess 4 in which is seated a casing4 which is apertured.

Mounted within the recess 3 is a resilient bar 5, shown clearly in elevation in Fig. 1, which has portions 6 thereof bent upon themselves and angled ends 7 which are held to the bottom of the recess by means of screws 8. p

A bar 9 has contracted ends 10 which engage registering apertures in the portions 6 of the bars which are bent upon themselves, a space intervening between the adjacent edges of the bars 9 and 5.

A yoke 11 is provided, in the walls of which the spindle ends 13 of the roller 14 Specification of Letters Patent.

are journaled, which roller bears against the outer edge of the bar 9.

Plates, designated respectively by numerals 15 and 16, one of which is shown in Fig. 4, have lugs 17 projecting from the opposite edges thereof and which are adapted to rest upon the upper edges of the walls of the yoke 1n the manner shown in Fig. 2, one plate being positioned upon either side of the resilient bar 5 and which constitute friction plates, cooperating with the two bars the roller 14 to hold the yoke in different adjusted positions. A lever 20, pivotally mounted on a pin 21 in the housing 22, engages registering apertures 19 in the yoke 11 and the short end of the lever projects outside the casing and forms a means whereby the lever may be tilted when it is desired to cause the yoke to be tilted upon the fulcrum points 23 or 24 which are formed by portions of the easing 4 being bent upon themselves, it being noted that said yoke is loosely mounted in said recesses. 1

Referring to Fig. 1 of the drawings will be seen a bracket member 26 which is apertured for the reception of the two bars and having its inner end angled and fastened by bolts 27 to the end of the sash, said bracket member serving as a guide for the sash as it is raised or lowered.

The operation of the device will be readily understood and is as follows When the window is closed, the weight rests upon the sill and the yoke will be positioned as shown in Fig. 1 and any attempt to raise the window without the manipulation of the lever 20 will cause the yoke to tilt and the sash will be frictionally held by the antifriction roller and the plates 15 and 16 to bind respectively against the bars 9 and 5. In order to allow the window sash tobe raised, the operator by tilting up upon the outer end of the lever 20 may cause the long arm of said lever to tilt the yoke upon the fulcrum point 24, thus relieving the bars from their frictional contact with the roller and plates 15 and 17, after which the sash may be readily raised. When the sash has been raised to the desired height, the weight of the sash coming upon the yoke will cause the same to tilt and the roller and friction plates will frictionally engage the bars and hold the window in an adjusted position. After the window has been raised and it is 5 and 9 and desired to move the same, it will be necessary, in order to move the sash either up or down, to first push down upon the projecting end of the lever 20 which will cause the yoke to tilt and release the friction mechanism.

By theprovision. of a window holding device embodying the features of my inven tion, it will be noted that, a. simple and ef ficient means is afforded whereby the sash may belocked closed orin any open position, making it necessary to manipulatethe lever before the sash may be moved in either. direction.v

Whatli claim to be 1. A window sash lock comprising, in combination with the frameFand sash, bars mounted upon the frame and spaced apart, a yoke carried by the sash and plates car new is ried by said yoke for frictionally engaging said bars, a roller pivotally journaled upon the yoke and engaging the edge of an adjacent bar, means upon the sash against which the yoke is adapted to fulcrum, and means upon, the sash for tilting the yoke to throw said plates out of en gagement with said bars;

2. A sash lock comprising, in combination with a recessed window frame and sash, bars mounted within the recess of the frame and spaced apart, a yoke extending about said bars, an-anti-friction Wheel carried by the yoke and engaging the outer edge of one of said bars, said bars being spaced apart, friction plates carried by the yoke, one positioned in the space intermediate the bars and the other bearing against the outer face of the inner bar, means upon the sash upon which the yoke is fulcrumed, and a lever carried by the sash and adapted to tilt the yoke.

3. A- sash lock comprising, in combination with a recessed window frame and sash,

I bars mounted Within the recess of the frame and spaced apart, a yoke extending about said bars, an antrfrl ction wheel carried by the yoke and engagmg the outer edge of one of said bars, sa1d bars being spaced I apart, friction plates carried by the yoke,

one positioned in the space intermediate the Copies of this patent may be obtained for five cents each, b y addressing the .a second bar bars and the other bearingagainstthe outer face of the inner cessed, acasing mountedtherein and havwith .a. recessed window frame and sash,

bars mounted within the recess of the frame and spaced apart, a yoke extending about said bars, an anti-friction wheel carried by the yoke and engagingthe outer edge of one of said bars, friction plates carried by the yoke, one positioned in the space inftermediate the bars and the other bearing against the outer face of the inner bar, said sash being recessed, a casing mounted therein and havingl aterally projecting fulcrum points for said yoke, the yoke being apertured, a lever pivotally mounted upon the sash and having an arm projecting through an aperture in the yoke, and means for guiding the sash as it is raised and lowered.

5. A sash lock comprising, in combination with a recessed window frame and sash, a resilientbar having portions thereof bent upon themselves and angled ends fastened to the recess of the wall of the frame, the bent portions of the bar having openings,

having projecting ends engaging said openings and spacing the bars. apart, a yoke having a portion surrounding said bars, a friction roller journal ed in the yoke and engaging the edge of one of said bars, plates supported by the yoke and positioned one in the space intermediate the bars and the other intermediate the end ofthe yoke and the adjacent face of said resilient bar, the adjacent edge of the sash being recessed and into which said yoke extends, fulcrum means within the recess of the sash, and a lever for tilting the yoke to relieve the friction roller and plates from frictional contact with the bars and yoke. In testimony whereof I hereunto affix my signature in presence of two witnesses.
